We want to make sure that all of our test environments are clean from
possible outside modification. This consolidates the list of used
environment variables in Rust-based and Python-based integration tests.
Note that there is also a similar list in `src/bin/bat/main.rs` which
is even more exhaustive (for bug report collection). However, some
of these variables can not possibly have an effect on test environments.
Do not ignore `BAT_CONFIG_PATH` if it doesn't exist. Both when
generating a new config file with `--generate-config-file` and
when attempting to read the config.
Also, provide a better error message in case the file can not
be created.
closes#1550
Fixed by implementing the proposal by sharkdp:
* Allow PAGER=bat, but ignore the setting in bat and simply default to
less. Unless of course, BAT_PAGER or --pager is used to overwrite the
value of PAGER.
* Disallow the usage of bat within BAT_PAGER and --pager.
Right now all tests pass even if we e.g. return
Ok(OutputType::stdout())
instead of doing
.chain_err(|| "Could not parse pager command.")?
so add a test to make sure this functionality don't break.
This is a regression test for the fix for issue #299. If that fix is
reverted, currently only one test ('header_padding') fails. But that
test is for a different use case, so add a dedicated regression test for
the particular use case issue #299 is about.
As mentioned on #1334 `bat` should not be used as a value for `pager`,
this change checks both the balue of `bat` provided as a parameter or
as an environment variable.
- using `echo` on 'windows' platforms requires process execution indirectly via the shell
- `printf` is available on all GHA CI platforms
- `printf` is *not* available on usual 'windows' platforms; so this is just temporizing, awaiting a true fix
